Liquid Penetrant Inspection

Penetrant testing (PT)/ Liquid Penetrant Inspection (LPI) is one of the oldest and most widely used methods for the detection of surface discontinuities in nonporous solid materials. From mid 20th century, the penetrant method has gone through a remarkable development and is now the most important method for the detection of surface defects and discontinuities.

Penetrant testing will help you find defects that are open towards the surface, like cracks and surface breaking flaws. The method is suitable for all non-porous materials such as steel, aluminium, copper, plastics, ceramics and castings. For more information on the penetrant testing method, see our Frequently Asked Questions.
